here it is explained how to set it to use jdk1.7 http://community.jaspersoft.com/%3Ca%20href%3D%22/comment/809527%23comment-809527%22%20class%3D%22permalink%22%20rel%3D%22bookmark%22%3EPermalink%3C/a%3E

I reported teh page break thingy on http://jasperforge.org/projects/jasperreports/tracker/view.php?id=4796 it turned to be a duplicate of http://jasperforge.org/projects/jasperreports/tracker/view.php?id=4760 still open

yes, we've seen it with page breaks as well (we added a explicit check to avoid user uploading such templates)

Also, I see the page and time governor settings are default to ON but the page and time out is default to 0 so they are ignored I think it would be better to default them to some safe numbers and have the admins make them greater if found the need

is there any way of setting jasperreports properties programatically instead of the config file? (so we enforce the setting thus not missing it by oversight when upgrading the jar file)

Great, I'll do that. Thanks

I understand Couldn't jasper include some known trouble makers (such as this one) detector on the template validator Bringing the server down is really *really* unacceptable Maybe also virtualizers could detect this case and avoid writing file to disk forever Just saying. I think I will add this check to our app so they don't fire me if someone brings the server down and I say "I knew this could happen but it is not possible to guarantee jasper won't kill the server" :-D Thanks. I will stop bothering you now :-)

I'm sure, I have tested this thoroughly Just run the attached sample templates and you will see It works without virtualization but hangs using the virtualizer I think this is not a "program" users are writing when they come up with a template xml. It is a configuration file. I think applications should validate configurations so they don't hang the server (not preaching you although it sounds like it :-)) I bet custom report support is a widely jasperreports use. If jasper doesn't have this check we will have to add it ourselves to detect the offending case, since we do have users uploading their own templates to the server and we cannot afford having a user hanging the server up

Thanks Teodor We, of course, fixed the report that time and got it to work OK once the problem was identified I think, however, no template should be able to bring a thread down or it will be very unsave to let app users upload their own templates (which we are using jasperreports for, basically -custom reporting support-) Please note that the report will generate fine if virtualization is not turn on, that's why I think the virtualizer is the one with the problem

I posted our particular case as a bug with a sample to reproduce http://jasperforge.org/projects/jasperreports/tracker/view.php?id=5189

we are seeing the same problem when pagination is on for the report and we have a report including two subreports, running the report eats all the memory it works fine if we turn pagination off. The report is not that big. It ends up having only one page

Teodor, hi We are seeing this with jasper 3.7.3 using this code: JRXlsxExporter exporter = new JRXlsxExporter();exporter.setParameter(JExcelApiExporterParameter.JASPER_PRINT, ((RPPrintJR) print).getJasperPrint());exporter.setParameter(JExcelApiExporterParameter.OUTPUT_STREAM, output);exporter.setParameter(JExcelApiExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);exporter.setParameter(JExcelApiExporterParameter.IS_FONT_SIZE_FIX_ENABLED, Boolean.TRUE);exporter.exportReport(); When I give the OK to try to open the file it opens with this message: Excel was able to open the file repairing or removing unreadable content: Removed feature: Hyperlinks from /xl/worksheets/sheet1.xml part Post Edited by damiankober at 04/05/2011 10:26

Sorry about my question. I don't use excel much. It was not possible the last time I checked so I'm assuming by your response it isn't yet :-)

which formats support links on the html textfields? Does excel?

great!
